Should you have spent the last year hiding from the world in a geodesic dome in the woods, you might not know that this refers to Wendy's giving a year's worth of nuggets to a youth who broke the world retweet record.

I contacted McDonald's to ask what might have happened with its copy-and-missing-link tweet. The company pointed me to its follow-up tweet about a lack of coffee.

Of course, we all mistakes. The overly speedy world of social media merely encourages them.

Yet this isn't the first time that Wendy's has been waiting to pounce on its larger rival.

Earlier this year, McDonald's proudly announced on Twitter: "Today we've announced that by mid-2018, all Quarter Pounder burgers at the majority of our restaurants will be cooked with fresh beef."

To which Wendy's replied: "So you'll still use frozen beef in MOST of your burgers in ALL of your restaurants? Asking for a friend."
